PROBLEMS AND PROSPECTS FOR THE INTELLECTUALIZATION OF AUTOMATIC CONTROL SYSTEMS
Introduction. The improvement of automatic control systems via their intellectualization is the important problem from both theoretical and practical points of view. The presence of adaptation and learning processes intrinsic to the natural intelligence makes it possible to consider the modern adaptive and learning systems as some intelligent control systems of the simplest type.
The purpose of this paper is to outline briefly the world-class results related to the efficient adaptive control and achieved in Intelligent Automatic Systems Department during the last 25 years and also to point out on problems of future research in this scientific area.
Results. A new adaptive control theory which has recently been completed represent the significant achievement to deal with the control systems in the presence of both parameter and nonparameter uncertainties. The main distinguishing feature of this theory is that it requires no information about the constrained membership set of unknown plant parameters and the bounds on arbitrary unmeasurable disturbances. Utilizing its methods, we can ensure the desired performance indices of the control systems with uncertain plants whereas the existing methods become quite unacceptable in the same situation.
Conclusion. Based on recent results concerning the adaptation and learning problems, we propose to take a next step toward to novel intelligent automatic control systems containing complex nonlinear plants. However, new perspective methods guaranteeing a perfect behavior of the closed-loop control systems, in particular, the stability of these control systems should be devised before implementing them in practical applications. This as yet unsolved scientific problem remains the subject of future theoretical research.
Keywords: adaptive and learning control system, automatic intelligent control system, parameter and nonparameter uncertainties, unmeasured disturbance, complex nonlinear plant.
